IMPROVEMENT lN APPARATUS FOR HARD-SIZING, COLORINGI AND WATER-PROOFINGPAPER.

Specification forming part of Letters Patent No. 149,316, dated April 7,1874; application filed July 28,1873.

. cation for a patent coincidently with this;

and consists in the arrangement of adjustable scrapers for removing thesuperfluous sizes from the surface of the fabric operated upon.

My apparatus consists of two vat-s, A and B, interposed between the lastpair of press-rolls O O and the drying-cylinders D D, of a Fourdrinieror cylinder machine. These vats are provided with guide-rollers e c eand carryingrollers f f, for the purpose of conveying the paper or othermaterial operated upon into and from the sizing compositions containedinthe vats. Each vat is provided with adjustable scrapers g g, forremoving the superfluous size from the surface of the paper or othermaterial.

In the accompanying drawings, Figure 1 is a vertical longitudinalsection, showing my apparatus interposed between the last pair ofpress-rolls, and the drying-cylinders of a Fourdrinier machine, and Fig.2 a plan of the same.

The dotted lines indicate the paper or other material under treatment,and the arrows indicate the direction in which it moves.

In sizing paper and other materials which vary in strength of tenacity,and in applying sizes which vary in consistency, it is necessary toregulate the tension to which the web is subjected by the scrapingprocess; hence the importance of the feature of adjustability, asapplied to the scraping mechanism.

I claim as my invention The adjustable scrapers g g, for acting uponopposite sides of the paper or other material operated upon, incombination with each other, and withthe vats A B, provided withsuitable guide-rollers, substantially as described.

In witness whereof I have hereunto signed my name this 24th day of July,1873.
